[resolved] Sub domains problem (12 posts)

Hi
I had a subdomain before activating multi site network in wordpress 3. Now after activating it, I can't use it as it was. How can I solve this problem? In multi site, I can't have separate sub domains created directly from cpanel?
Thanks in advance

Yes, my problem somehow has been solved.
I've added the wildcard record, added "wiki" to the banned list, deleted the old subdomain and created a new one, but I didn't put these lines in .htaccess:
RewriteCond %{HTTP_HOST} wiki.mydomain.org
RewriteCond %{REQUEST_URI} !wiki/
RewriteRule ^(.*)$ wiki/$1 [L]

I don't know exactly how this problem solved (or does it exist in the first place!?), maybe the support from my host have done something or maybe just deleting and recreating the subdomain was the solution.

Now I have a weird problem. My problem did fix at the first by deleting the subdomain (i.e wiki.mydomain.org) and recreating it. The problem now is it works fine for some days (say 4, 5 days) and then it'll redirects to main domain saying that this subdomain is banned from register (I added wiki to the banned site names' list). What is the problem and is that a problem with my host's settings?
